In search for email addresses

I am about to enter German and Austrian market with my products and therefore I need to find contacts - email addresses - of new distributors and sellers of my products (wholesalers or retailers). I intend to sell nature friendly, organic, biodegradable dental equipement and therefore I need to focus on the retailers or wholesaler working in the field of bio/organic cosmetics, grocery, or other "green" items - It is very important to find e-mail addresses from this sector, so the new sellers find my products interesting and suitable for completing they product portfolio.
